On the Use of Abatement Cost Curves in Integrated Assessment Modelling – Implications of Dealing with Multi-pollutant Multi-effect Problems

Abstract

This paper critically reviews the current state-of-the-art of integrated assessment modelling (IAM) of air pollution control strategies based upon single abatement cost curves, elaborating on the specific implications of multi-pollutant multi-effect analysis for their further use in modelling studies. Starting from this analysis, a new approach towards modelling emission control options is discussed, which combines the concept of transparency and simplicity – among the most criticised aspects of current integrated assessment models – with a real-world modelling approach of abatement options, both technical and non-technical. In the second part of the paper, the application of evolutionary algorithms for IAM is described, giving a brief introduction of advantages and implementation in a currently running research project.
